This is the first in a series of (long overdue) posts related to odd bugs and behavior experienced in the Cisco Unified Border Element (CUBE) which is built into Cisco IOS. I will spare you all the details, but high level our environment looks like this:
- Cisco Unified Communications Manager (CUCM) – multisite deployment with centralized call processing with geographical diversity
- Contact Center – Cisco CVP including Call Studio, UCCE, Nuance ASR/TTS, Cisco Unified Presence Server (SIP Proxy)
- SIP Trunks with CUBE for Local/Long-Distance and Inbound Toll-Free
